70=A=Lw
L=2w-4
70=(2w-4)w
70=2w²-4w
70=2(w²-2w)
35=w²-2w
0=w²-2w-35
0=(w+7)(w-5)
-7=w or w=5
Measurements aren't negative
w=5 ft
L=2(5)-4
L=6 ft
Answer:
The distance between (5, 7) and (-2,-2) is 11.4 units.
Step-by-step explanation:
We are given the following in the question:
Points:
(5, 7) and (-2,-2)
We have to find the distance between the two points.
Distance formula:
Putting values, we get,
Thus, the distance between (5, 7) and (-2,-2) is 11.4 units.
Answer:(theta) =π only
Step-by-step explanation:
-4cos(theta)+1=5
Subtract 1 from both sides
-4cos(theta)+1-1=5-1
-4cos(theta)=4
Divide both sides by -4
-4cos(theta) ➗ -4=4 ➗ -4
cos(theta)=-1
(theta)=cos(inverse)(-1)
(theta)=180
(theta)=π
Given a data on the relationship between the number of students that have ever gone snowboarding and <span>the number of students that own a skateboard.</span>
Given from the survey that <span>35
of the 99 students who own a skateboard have snowboarded and there
were 13 students who have snowboarded but do not own a skateboard, and
147 students who have never gone snowboarding and do not own a
skateboard.
We represent the above information in a two</span> way frequency table.
Have Snowboarded Never Snawboarded Total
Skateboard 35 64 99
No Skateboard 13 147 160
Total 48 211 259
Answer:
Yes, that is correct.
Step-by-step explanation:
W = x
L = ?
A = x^2 + 12x
(x^2 + 12x)/x = x + 12
L = x + 12
Subbing in 10 for each X, we get:
Perimeter: 64
2(10) + 2(10 + 12) = 20 + 44 = 64
Area: 220
10 * 22 = 220
